Read the following passage to answer the question below.
Element Z is a soft powdery solid with poor conductivity. It bonds with fluorine to form a product with the formula ZF6 which is a colorless, odorless gas. The Lewis Dot structure for Element Z is shown to the right.
Element Z must be oxygen because the product is a gas and it matches the Lewis Dot structure.
Element Z must be sulfur because of the description of the element and it matches the Lewis Dot structure.
Element Z must be sodium because it is a metal that can bond with fluorine.
Element Z must be chlorine because it is also halogen and has the same number of electrons as fluorine.
